Expanded Lie Point Symmetry

A software "Expanded Lie Point Symmetry", coded as a maple package, was developed by Alexandre Sedoglavic and François Ollivier [76] , [100] allowing to reduce the number of parameter of parametric (ordinary) differential/difference/algebraic systems when the considered system have affine expanded Lie point symmetries. Given a model, ELPS allows to test its identifiability/observability and to reformulate the model if necessary.
